To all zo/mm t may conce/rn,

Be it known that I, GUs'rAlf JOHNSON, a citizen ot the United States, and a resident oill the city oit Chicago, county ot' Cook, and State oit illinois, have invented certain new and usetul Improvements in l/Veather-Strips, ot' which the following is a specification.

My invention relates to improvements in weather strips, and has for its object the production of a construction which will be din-able and economical.` and of high etliciency in use.

Other objects will appear hereinafter.

`With these objects in view, my invention consists in the combinations and arrangements ot' parts hereinatter described and cl a :im ed My invention will be best understood by reference to the accompanying drawing Yforming a part of this specification, and in which-m Figure 1 is a sectional front elevation of a. window sash trame equipped with weather strips embodying my invention', Fig. 2 is a vertical section through the sash frame, the lower sash being shown in elevation, the upper sash being removed, Figs. 3 and 4 are enlarged detail fragmentary sections taken on substantially lines ai :u and jz/ y, respectively, of Fig. 1, and Fig. 5 is an enlarged detail elevation ott one ot the parts ot' the weather strip, (jletached.

The preferred form of construction, as illustrated in the drawing. comprises a window sash frame l in the opposite sides of which are provided the usual inner and outer or lower and uppersash grooves 2 and 3, respectively. Arranged in the frame l. with their lateral edges slidably engaging the grooves 2 and 3, are the inner and outer or lower and upper sashes t and 5, respectively.

Arranged in the bottom oi each of the grooves 9 and 3 is a strip 6 termed preterably of sheet metal, which is secured in position by screws 7. Formed in the strip 6 adjacent one ot the longitudinal edges thereoit, is an outwardly projecting Tshaped tongue 8. The tongue 8 is embraced by or interdoclringly engaged with a channel strip 9 which is mounted in a longitudinally extending groove 10 formed in the lateral edges of the sashes t and 5, as clearly shown in Fig. 2?, the strips 9 being secured in position by screws 11 which pass therethrough at intervals.

Each of the strips 9 is formed at its outer edges with inwardly projecting flanges 12 which are adapted to engage behind the laterally projecting head portions of the corresponding tonguo 8, the inner edges thereof being adapted to 'forcibly engage against the opposite sides of the web or leg of said tongue, as clearly shown. The head of each of the tongues S is of a width correspond ing with the inside width of the correspond ing strip 9.so that the longitudinal edges ot' said head engage against the inner surfaces of the opposite sides of the channel. lVith this arrangement it will be seen that a double joint is effected between corresponding strips 6 and 9, which results in the effectual exclusion of the weather. The engagement oi the flanges 12 behind the laterally projecting portions et' the corresponding tongue 8, obviates all possibility of dis` engagement of cooperating parts of the weather strip where the window sash is very loose in the frame or upon excessive shrinking oil the sash in the iframe. The strips G in the respective grooves 2 and 3, are positioned for engagement with the strips 9 carried by the corresponding sashes when the latter are in normal position, hence said strips 6 do not extend the entire length of said grooves, this being unnecessary.

Arranged between the contiguous sur- 4faces of the overlapping transverse bars of the saslies 4 and 5 when the latter are in normal position) and the lower transverse bar oil the sash et and the adjacent side of the sill of frame '1, is an elongated metallic strip 13. The edge 14C of each oi. said strips 13 is bent inwardly into engagement with a groove 15 formed in one ot the contiguous surfaces between which the same is arranged, the extreme edge 1G of the portion 14E being turned back in order to automatically engage one side of the groove 15, when the portion 14- is inserted therein, to securely t'asten the latter in position. The opposite edge of each of the strips 13 is free and is normally inclined outwardly so as to be adapted to 'forcibly engage against the adjacent contiguous surface, as clearly shown in Fig. fi. '[he extreme edge 17 of said free edge portion is bent at right an* gles to the body thereof for loosely engaging a groove 18 which is formed in the same surface as bears the groove 15. One ot' the strips 13 is preferably carried by the lower bar of the upper or outer sash, the

loWer edge portion of the strip being free for obvious reasons. The other of the strips 13 is secured to the lower bar of the sash e, the lower edge portion of said strip being secured and the upper edge portion free for engaging against the adjacent side of the Window sill, as will be readily understood. Thus provision is made for effectually excluding the Weather from the transverse joints in the Window construction. By the use of both ofr the strips described, that is of those cooperating With the lateral edges of the sashes and those cooperating with the transverse edges thereof,

the exclusion of the Wea-ther Will be positive parallel edges oit' the C-shaped member and and effectual.

lfilhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable or' variation and modication Without departing fromfthe spirit of the invention. l therefore, do not wish to be limited to the exact details of construction set forth, but desire to avail myself of such variations and modifications as come Within the scope of the appended claim.

Having described my invention, What I Copies of this patent may be obtained for arranged entirely Within the groove, and co- Y acting members on the adjacent portion of the frame, said coacting members being substantially T-shaped and comprising a securing base, a web portion consisting of spaced resilient members fitting snugly against the a head portion fitting snugly against the opposite sides of said C-shaped member, substantially as described.
